Conventional georadar provides high-resolution sections of the surveyed surface.
When the size and depth of the study targets are defined, a proper frequency (or frequencies) is selected and the survey is carried out with the appropriate antenna. Generally georadar studies are restricted to a few meters from the surface.
It is a methodology very demanded due to the lateral resolution, rapidity in data acquisition and low cost. Georadar is a very useful tool that requires qualified personnel for the correct interpretation of raw field data.
3D Multifrequency GeoRadar
The state-of-the-art in GPR technology is represented by the new 3D multifrequency systems. The main advantages of these units are:
- Broader bandwidth.
- Multiple Sensors in a single antenna.
- Error free in positioning of parallel profiles.
- Pulse velocity determination.
- Survey speed.
- Detailed 3D models.
This type of georadar is a revolution in the geophysical community due to their versatility, capacity of definition and mainly by the reduction of the associated economic costs.
